I provide a framework for understanding debt deleveraging in a group of _nancially integrated countries. During an episode of international deleveraging world consumption demand is depressed and the world interest rate is low, reecting a high propensity to save. If exchange rates are allowed to...

This paper develops a two-country multi-frictional model where the freeze on liquidity access to commercial banks in one country raises unemployment rates via credit rationing in both countries. The expenditure-switching channel, whereby asymmetric monetary shocks traditionally lead to negative...

Currency and financial turmoils in international capital markets have been the focus of an extensive theoretical research which started around 30 years ago. This paper provides a synthetic overview of this theoretical modeling. We analyze the basic analytical framework corresponding to the...

I propose a unified model of domestic bank runs, sovereign debt issuance and international reserve accumulation. Banking fragility gives rise to endogenous costs of default that support sovereign debt capacity. It additionally brings about a financial stabilization role for international...

We propose a "debt view" to explain the dominant international role of the dollar. We develop an international general equilibrium model in which firms optimally choose the currency composition of their nominal debt. Expansionary monetary policy in downturns prevents Fisherian debt deflation...

How costly are sovereign debt crises? In this paper we study output losses during sovereign default and debt renegotiation episodes since 1980. In contrast to previous work, we account for the severity of default and not only for its occurrence. Specifically, we distinguish between “hard”...

We consider how fear of model misspecification on the part of the planner and/or the households affects welfare gains from optimal macroprudential taxes in an economy with occasionally binding collateral constraints as in Bianchi (2011). On the one hand, there exist welfare gains from...

This paper proposes a quantitative theory of the interaction between private and public debt in an open economy. Excessive private debt increases the frequency of financial crises. During such crises the government provides fiscal bailouts financed with risky public debt. This response may cause...

Protests and fiscal crises often coincide, with complex causal dynamics at play. We examine the interaction between tax revolts and sovereign risk using a quantitative structural model calibrated to Argentina during the Macri administration (2015-2019). In the model, the government can be...
